We’re halfway through the Republican National Convention, and the bulk of the work is behind us. Republican delegates have adopted a conservative platform, withstood threats of a floor revolt and overcome internal divides to nominate Donald Trump to be their party’s candidate for president.

Now comes the bigger test. Two of Trump’s former rivals are set to speak at tonight’s event, along with the runner-up to be his running mate. The evening will be capped by a speech by the party’s nominee for vice president, Indiana Gov. Mike Pence, who hopes to erase awkward memories of his debut last week.

The speechifying begins at 7:30 p.m. Here are five things to watch:

Pence's time to shine: Republicans are desperate for a flawless night after previous hiccups, and Pence's speech will be front and center. Trump picked him because of his appeal to conservatives, and tonight's speech gives him the chance to prove his worth.

The runner-up's spotlight. Former Georgia lawmaker Newt Gingrich came in second place in the hunt to be Trump's running mate, but he was still handed a coveted speaking gig. Will he outshine Pence? Will he bring up his call to test all Muslim citizens in the U.S. on whether they believe in Shariah? Will he steal the show? Stay tuned.

Cruz's crap shoot. Texas U.S. Sen. Ted Cruz still hasn't endorsed Trump, and he may not endorse him tonight. But you can expect a kind word or two from the former presidential candidate tonight. Cruz, Trump's most formidable rival, was labeled "Lyin' Ted" by the Trump. Tonight they could bury the hatchet.

The other also-rans. Cruz isn't the only former Trump rival to address the crowd. Florida U.S. Sen. Marco Rubio, who also hasn't endorsed Trump, will deliver a televised address. And Wisconsin Gov. Scott Walker, another ex-candidate rumored to have an eye on 2020, is set to speak.

Trump factor: Nominees typically command the stage once or twice during the four-day event. Thus far, Trump has made an appearance both nights, and he's set to show up again tonight. He made a smoke-filled entrance Monday to introduce his wife, Melania, and he appeared on video Tuesday after he was formally nominated. He said he'll be back tonight to show up on stage with Pence, teasing that he might have a surprise in store. Huge.
